ABSTRACT

The densities and viscosities of ternary solutions (erythritol/xylitol/mannitol + l-ascorbic acid + water) and binary solutions (erythritol/xylitol/mannitol + water), were measured under atmospheric pressure and the temperature range of (293.15 to 323.15) K. The apparent molar volumes (Vf), the limiting partial molar volumes (Vf0) and the limiting partial molar volumes of transfer (?trVf0) were calculated through densities, respectively. Guimaraes equation and extended Jones-Dole equation were applied to correlate the densities and viscosities of erythritol/xylitol/mannitol in l-ascorbic acid aqueous solutions, respectively. The free energy of activation per mole of solvent (?micro10?) and solute (?micro20?) were obtained through the viscosity B-coefficients. These significant parameters are helpful to understand the interactions in sugar alcohols + l-ascorbic acid + water ternary solutions.
